What you are already having i.e. aortic stenosis and cardiac stiffness ( most probably due to cardiac amyloidosis ) may cause the left ventricle to work harder to pump blood into the aorta and deposits of an abnormal protein (amyloid) in the heart tissue, which make it hard for the heart to work effectively.
The pituitary gland is a gland in the brain which produces chemicals called hormones (an endocrine gland). Hormones are chemical messengers which help different organs in the body communicate with each other. The pituitary gland is one part of a messenger system.he pituitary gland is sometimes called the master gland because it controls several other hormone-releasing glands. Some of the glands the pituitary gland controls are the thyroid gland, the ovaries, the testicles (testes) and the adrenal glands.
The pituitary gland is a small endocrine organ that controls a multitude of important functions in the body. It is divided into an anterior lobe, intermediate lobe and posterior lobe, all of which are involved in hormone production.
